KEnosENE-BURNI-ive TORCH.

Application led December 18` 1918.

To coZZ'wwf/a t may concern:

Be it known that I, Crm1: Ti. HmksoN, a citizen of the United' States of America, residing at Newaygo, in the county ol' Newaygo and State of Michigan, have invented certain new and useful lmproveinents in Kerosene-Burning Torches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to torches burning kerosene as fuel, and it is a primary object and purpose of the invention to produce a torch of this character in which a particularly effective combustion, and one that is steady and sustained at all times is made. Further objects of the invention, subsidiary to and contributive to the primary object, are the provision of a novel means of straining the generated gas before it passes out ot' the nozzle to be burned, a novel and especially effective means for heating the fuel and generating it into a gas, and a novel construction of nozzle which contains a reservoir for holding a certain supply oii' gas from which the torch is fed steadily and continuously irrespective of variations in pressure which may arise farther back in the fuel conduits. All of these features together with many others not at this point specifically stated, will appear fully and .in detail as understandingr of the invention is had from the following description, taken in connection with the accompanying drawing showing a practical working enibodiment of the invention, in which drawing,-

Figure 1 is a vertical section taken longitudinally of the torch substantially on the plane of line 1"-1, of F ig. 2.

Fig. 2 is a transverse section taken substantially on the broken line 2 2, of Fig. l.

Fig. 3 is an enlarged vertical .section through the nozzle.

Fig. 4 is a similar enlarged vertical section through the gas straining portion of the device.

Like reference characters refer to like parts` in the different views of the drawing.

In construction, the torch includes a hollow cylindrical body or head 1, open at one end and slightly taperin toward said open end as indicated at 2. he opposite end is Specification of Letters Patent.

closed by a back 3 formed integrally with the head 1 which is Jformed with a central opening t as shown. In the lower wall of the head a depression 5 is niade serving to hold a quantity of fuel which may bc burned to heat the kerosene carrying pipes within the head as later described, when the torch is first lighted after it has become cold. There are also provided a triple series of holes G through the rear part ol the head spaced from each other, and in practice there are several of such holes in each. row around the head, the holes of a row being equally spaced from each other.

The kerosene fuel is ied through a pipe 7 from any desired tank, the fuel being under pressure to force it through the pipe. Near the front end of the head the pipe 7 is turned by means oil unions S to connect with a pipe 9 positioned lengthwise oi and within the head, it being joined by suitable unions 10 and a short length ot pipe with another pipe 11 also lying lengthwise of the head near 'one side, this in turn connecting through suitable connections 12 with a pipe llilower in the head, which, through unions 111 and a transverse pipe connects with an oppositely disposed pipe 16 which, at its front end is connected with an upper pipe 17 lying in practically the same plane with pipe 11 but at the opposite side ot the head 1, from which, at its rear end a connecting pipe 18 leads to an outlet pipe 19, the saine passing to the rear through the back 3 oit the head. The series of pipes 9, 11, 13, 16 and 17 are located on the inner sides of and adjacent to the walls of the head. whereby an unobstructed space is provided in rontot the opening 4 through which the gas mixed with air taken through openings ile and 6 may freely pass and burn, heat being given off suiiicient to generate the kerosene in said pipes into a gas as will be obvious. This construction makes a very elfective generating coil which, as before stated, may be initially heated by burning fuel contained within the depression at The outlet pipe 19 leads into a Tunion 20 which in turn is connected to a T-union 21t a short pipe 22 extending therefrom toward the head. 1 and carrying a nozzle 23 at its end, the same coming directly back of the opening l as best shown in Fig 1.

The union 20 contains a gas straining or screening apparatus constructed as follows: In the end of the union opposite to that into which the pipe 19 is inserted, a hollow cylindricalistem or neck 27 is inserted connecting to the union by threading therein as shown. This stem is formed with a squared head 28 for threading it to place, the head coming against a gasket 29 disposed between it and the end of the union. The stem 27 is formed with a plurality of openings 30 through its sides and within the stem a section of screen 31 is rolled to tubularl form and inserted whereby the gas coming through the pipe 19 has to be strained through the screen before it can pass upward through the union 21 and to the nozzle. The screen may be held in place by abutting against suitable shoulders 30 made in the union as shown. In practice I have used a 14 mesh iron screen as best suited for the purpose and with this few if any particles liable to obstruct the nozzle can get by. And at any time it is easy to remove the screen to clean the same.

The nozzle screws on to the end of the short pipe 22 and is formed with a relatively large compartment or chamber 32 to serve as a reservoir of gas from which it passes outwardly through the opening 33 in ythe end of the nozzle. A plug 34 is screwed into the end of the pipe 22 within the nozzle and has a hole 35 bored lengthwise foi" a distance from which a plurality of branches 36 lead to the outer sides of the plug, the diameter of hole'35 and branches 3G being slightly less than the diameter of the outlet hole 33, any particle of matter in the gas which has passed the screen and through the passages 35 and 36 necessarily passing freely through said outlet. 'Io strengthen and support the nozzle and hold it in position at all times, a bar 2st is attached to the head 1, extending to the rear therefrom, it serving to carry a member 25 connected to the union 21. The pipe 7 is also held by a sleeve 26 through which it passes, this sleeve being lirmly connected to the bar 24, as shown.

A torch of the construction described is fully practical 'as shown from actual practical service lfor a considerable time. rIhe heating coil is very effective for the generation of gas from kerosene fuel, the screen construction serves to supply the gas to the nozzle minus any obstructing particles, and the chamber 32 in the nozzle beyond the small openings 35 and 3G keeps the gas under steady and continuous How, there being no danger' of back draft with a conscquent extinguishment of the llame. All of these features combine to produce a particularly cllective and serviceable torch.

I claim:

1. In a device of the character described, an elongated hollow head open at one end and closed at its rear end by a back, said back having a central opening therethrough, and said head adjacent its rear portion be ing provided with a plurality of air openings in its sides, a coil within the head in which fuel is adapted to be changed by heat from liquid to gaseous state, means to supply liquid fuel to the coil, an outlet pipe carrying the gaseous fuel from the coil a nd passing to the rear through the back oi" the head, a nozzle including a head having` a relatively large chamber therein, said nozzle being located directly back of the central opening in the back of the head, a pipe on to which said nozzle is secured, a plug provided with passages of small dimensions inserted into the end of said pipe and located within the chamber of the nozzle, and connections between said last mentioned pipe and the outlet pipe for carrying the gaseous fuel to the nozzle, substantially as described.

2. In a device of the character described. a hollow head open at its front end and provided with a central opening in its rear end, a pipe, a nozzle located directly back of said opening, said nozzle comprising an enlarged cap threaded on to the end of a pipe, and provided with an outlet opening` in its end, there being a relatively large chamber formed between the end of the pipe and the cap, a plug detachably inserted into the end of the pipe within said chamber, said plug having passages there through of dimensions less than the dimensions of the outlet opening to the nozzle, and means to supply gaseous fuel under pressure to said pipe, substantially as described.

In testimony whereof I aiiix my signature.

CLAIR L. HINKSON.
